Crash after selecting a *certain* directory

[Paul Matthijsse]

Hello, the following has happened several times, no clue why or how to resolve.

I’m editing a photo in a certain directory and ART crashes (very rare but sometimes this happens). I restart ART and go back to that dir in the Navigator > ART freezes. So I made a debug build to see what happens, below is the output: segfault. When I restart ART from the command line it outputs a glibmm error, see below, below.

I cleared the cache from within ART, that changes nothing. I renamed ./cache/ART to .cache/ART.off, but nothing changes either. Any idea what’s going on here?

When working in any other directory ART behaves normal. The “problematic” directory has a “normal” name (no spaces or special chars), as have the files in it.

[agriggio]

hi,

Can you please provide a backtrace? (See rawpedia).

Also, this is most likely caused by one specific image and arp sidecar. If you can isolate the problem and attach the offending files, that would also be great (but maybe a backtrace is enough)

Thanks for reporting!

[agriggio]

thanks. From there, in gdb, you can type the following:

(gdb) up
(gdb) print fname

this should show the offending file. Then you can maybe upload it together with the arp so I can understand what is going on. Thanks!

There’s no arp file, I deleted all of them to find out what happened…

[Paul Matthijsse]

Hi Alberto, I moved all the files from named directory and re-added them one by one. ART crashes on the following file, it was edited in ART and has no arp file because I deleted them all to find out what happened… Still don’t understand what’s going on…

‌

[Paul Matthijsse]

Hmm, if I rename the first offending file to index2_3xup.jpg.off, the crash does not happen…

[Paul Matthijsse]

Hi Alberto, I did some more testing. I copied the two original files above (original means: not edited in ART yet) to a new folder. I start ART in debug mode, navigate to that dir and open the second photo, the young lady with her mother. I use the tone equalizer to balance the tones, I save the file, everything ok. I open the other photo, the first one, do the same kind of editing and save. Then I see the following debug msg.

The Navigator shows only 3 images BUT the file has been saved and is readable in gThumb and Geeqie. Only thing: in both applications the thumbnails of the processed photos are corrupted (see attachment), but the files show up fine. Hitting F5 to refresh the Navigator leads to a crash.

Any ideas?

‌

[Paul Matthijsse]

Hello Alberto, some more info. I start ART in debug mode, I open the original photo of the young girl, set Tone Equalizer - Midtones to +65. An arp file is produced. Now I save the photo, the lines “Empty input file” appear again, the Navigator shows two photos instead of three (should be two originals and one saved), although the file is saved, again with corrupted thumbnail. There are differences between the jpg.arp and the jpg.out.arp, a diff produces the following output:

Hi,

I think you are conflating different problems here. The original problem was a segfault when reading a certain file. I can reproduce it with the first jpg you attached. So let’s keep this issue to that.

If you experience file corruption problems, please open a different issue, thanks!
